Comment (by Dave-Allured):

 This is not a `libomp` or Python problem.  This started with a recent
 commit for `openssl3`.  It looks like "older systems" are affected, also
 `vtk` and probably several other ports.  From above for 10.13:

 `openssl3 -> cctools -> llvm-10 -> xar -> openssl -> openssl3`

 https://build.macports.org/builders/ports-10.11_x86_64-builder/builds/280248/steps
 /install-port/logs/stdio

 `openssl3 -> cctools -> llvm-9.0 -> xar -> openssl -> openssl3`

 10.10 for `vtk` is also affected.  Here is the recent commit for
 `cctools`, October 29:

 https://github.com/macports/macports-
 ports/commit/d8401b989decbcddbe01c0f4830fc95e363c24e3

 It is not clear to me where the best place to break this cycle would be.
 Insights, anyone?
